Chance C705-0249 Backup Current Limiting Fuse

Chance C705-0249 Backup Current Limiting Fuse is a high-voltage protection device designed for 15 kV circuits, delivering current-limiting protection in SLC-90 configurations. It carries a continuous current rating of 500 A and an interrupt rating up to 50 kA, enabling rapid fault clearance while minimizing energy transfer to downstream equipment. Identified by the C705-0249 designation, this unit is part of Chance's current-limiting fuse lineup and is associated with SLC-90 protection assemblies used in 15 kV service. The model is intended for use in electrical distribution hardware where backup current-limiting protection is required and where establishment of reliable fault isolation is important for protecting upstream and downstream components. When installed in compatible switchgear, the C705-0249 provides a dedicated backup element to improve protection coordination in 15 kV networks. Typical environments include substations and industrial facilities where 15 kV protection is required.
